It is yet another object of the present invention to provide anapparatus of the aforedescribed type wherein the filter means includesfirst and second filter members having elongated openings therein.

It is still another object of the present invention to provide filtermembers, as above, wherein the first filter member is of a generallyinverted cup-shaped configuration and the second member is of a flatconfiguration, and wherein the longitudinal axis of the openings in theinverted cup-shaped member are disposed substantially perpendicular withrespect to longitudinal axis of the openings in the flat member.

It is yet a further object of the present invention to provide anapparatus of the aforementioned type, wherein there is provided amagnetic member interposed between the filter members and the balingdevice to prevent undesirable metallic members, such as staples, fromreaching the baling device.

BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and other objects,features and advantages of the present invention will become moreapparent from the detailed description hereinafter considered inconjunction with the accompanying drawing, wherein:

FIG. I is a front elevational view of a combination shredding and balingapparatus constructed in accordance with the principles of the presentinvention with a portion thereof being shown in section;

FIG. 2 is a perspective view of the flat filter member employed in theapparatus depicted in FIG. 1; and

FIG. 3 is a perspective view of the inverted cup-shaped filter memberemployed in the shredding and baling apparatus of FIG. 1.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawingsand, more particularly to FIG. 1 thereof, there is shown the combinationshredding and baling apparatus of the present invention which isgenerally designated by the reference numeral 10. The apparatus includesan endless belt type of conveyor 12 driven by means of a motor 14. Theconveyor 12 carries paper, books, magazines and similar paper productsto the inlet conduit 16 of a conventional rotary-type shredding device18 which includes a mounting base 20 which contains driving means foroperation of the shredding device I8.

The outlet conduit of the shredding device, generally denoted by thereference numeral 22, and comprising a plurality of connected sections24, is connected to and opens into a housing 26. The section 24 directlyconnected to the device 18 is of inward-tapered configuration to providea high-pressure area at the outlet 27 of the shredding device.

Pivotally mounted within the housing is a first filter member 28 havinga generally inverted cup-shaped configuration and also having aplurality of elongated openings 29 formed in the top and side wallsthereof. As best seen in FIG. 3, the member 28 has a sleeve 30 formed atone end thereof within which is disposed a rod 32. The ends of the rodare journaled in bearings 34 to thereby permit pivotal movement of thefilter member 28. The forward end of filter member 28 is held insupported engagement by means of a right-angle bracket 36 suitablysecured to the inner surface of housing 26, such as by welding, whichbracket also limits the pivotal movement of the filter member 28.

A second filter member 38 having a substantially flat configuration anda plurality of elongated openings 40 is also mounted within housing 26and positioned above filter member 28. As best seen in FIG. 2, themember 38 has a sleeve 42 formed atone end thereof within which is a rod44. The ends of rod44 are journaled in bearings 46 to permit pivotalmovement of the filter member 38. The forward end of member 38 is heldin position by means of a support member (not shown) whose position isadjustable by means of an arcuate adjusting slot 48 and an adjustingscrew 50.

Connected to the upper end of housing 26 is the inlet end 52 of a vacuumpump 54 operatively driven by means of a motor 56. The outlet end 58 ofthe pump is securely connected to one end of an air-pervious chute 60which, by way of example, may be fabricated of a canvas material. Theother end of the chute 60 is securely connected to the inlet end of arefuse container 62.

Depending from the housing 26 is an integrally formed passageway 64which is connected at its lower end to a baling device, generallydenoted by the reference numeral 66. The passageway 64 which herein isgenerally of annular configuration, includes an entrance door 68 whichprovides access to the baling device 66.

In the operation of the apparatus 10, paper, books and the like arecarried by the conveyor 12 to the inlet conduit 16 and deposited thereinand fed to the rotary shredding device 18 which shreds the material fedtherein into relatively thin paper strips. The rotational movement ofthe blades 70 (shown in phantom) of the shredding device 18 causes theformation of a low-pressure area at the inner end of inlet tube 16 andforms an increased pressure area at the inner end of the outlet conduit22, much in the same manner as a rotary pump. This pressure differentialcauses the material to be sucked into the inlet conduit 16 and to beforced outwardly, after shredding, into the outlet conduit 22.

The vacuum provided to the housing 26 at the inlet end 52 of the vacuumpump 54 is also present at the outer end of the. outlet conduit 22 andin conjunction with the increased pres sure at the inner end of theoutlet conduit, permits the shredded paper strips to pass upwardlythrough conduit 22 into housing 26.

Attention is directed to the fact that the longitudinal axes of theelongated openings 29 in the top and sidewalls of filter member 28 arein linear and parallel alignment. Similarly, the longitudinal axes ofthe elongated openings 40 in the filter member 38 are in linear andparallel alignment. However, the longitudinal axis of the openings 29and 40 are disposed in substantially perpendicular relationship with oneanother. In a preferred embodiment of the invention the openings 40 aremade somewhat smaller than those of openings 29, the purpose of whichwill now be described in detail.

The shredded paper strips of significant size in the housing 26 willpass downwardly into passageway 64 and then into the baling device 66.Other ones of the paper strips will pass upwardly into the interior offilter member 28 due to the vacuum present in housing 26 by virtue ofthe vacuum pumps 54, and if too large to pass through the openings 29therein will also drop downwardly into the passageway 64. Those paperstrips of smaller size will pass through the openings 29 in the top andsidewalls of member 28 and present themselves at the bottom surface ofthe filter member 38 where the longitudinal axes of openings 40 areperpendicular to those of openings 29 through which the last-mentionedstrips had passed. Thus, if the size of these strips is significant theywill be unable to pass through openings 40 and will tend to falldownwardly past the sides of member 28 and then into passageway 64.

The parties and strips which are small enough to egress through bothopenings 29 and 40, which will include small particles of paper, dustand other small sized debris, will flow into the vacuum pump inlet 52and through the pump 54 into the outlet 58 and then downwardly throughthe chute 60 into the refuse container 62.

As discussed hereinbefore, the chute 60 is fabricated of an air-perviousmaterial, such a s canvas, whereby the pressurized air appearing atoutlet terminal 58 is permitted to diffuse outwardly therefrom, whilethe small sized particles of debris and dust pass therethrough intocontainer 62.

It will be apparent that in the shredding of books and magazines, forexample, some of the undesirable particles presented in housing 26 willbe metal, such as staples. While some of these small metal particleswill tend to pass through the filter members 28 and 38, and thus bedeposited in container 62, other ones of these metallic particles willpass directly downwardly into passageway 64 and ultimately into balingdevice 66. In order to prevent the particles from passing throughpassageway 64, the same may be provided with internally positionedmagnetic members 70 which will attract the metallic particles andprevent the same from entering the baling device.

While I have shown and described the preferred embodiments of myinvention, it will be readily apparent to those skilled in the art thatthere are many changes, modifications and improvements which may be madetherein without departing from the spirit and scope of the invention.
